Second hand

I was able to keep the finger design from my first design iteration but dropped the hand segment concept. On the second design iteration I am locating the servos in the forearm and connecting them with the hand and fingers with sheathed tendons.

So far I have the finger and hand bone analogs done and am working on the connection between the metacarpal bone {hand} and the carbal bones {wrist}. Here you can see the progress so far.

You can see attached to the middle and little fingers a first try at making a connector between fingers and carpal bones..  It's clearly too big and I'm already printing a second, more compact version.  I've used the dimensions of my own hand in this design.
